Guncotton

Guncotton, form of cellulose nitrate resembling cotton, used in explosives and propellants. Guncotton is prepared by first treating cotton or wood fibers with a mixture of strong nitric and sulfuric acids. After this nitration process, the fibers are washed, ground, pressed, and dried. Extreme care is necessary in the handling and storing of guncotton, as it can be ignited by impact, friction, or excessive heat.
